Comparison of several non-linear-regression methods for fitting the Michaelis-Menten equation

An evaluation of three methods for fitting the Michaelis-Menten equation to sets of data with a common Michaelis constant but different maximum velocities [proceedings].

and substrate are in direct contact, and the solubility of chlorpromazine therefore appears greater. These previous investigators have fitted data to a normaf Scatchard plot, though there are signs of the plots having been forced through the points at low concentrations. The present results, taken in conjunction with previous ones, indicate a close similarity between chlorpromazine binding to a...

When does the Michaelis-Menten equation hold for fluctuating enzymes?

Enzymes are dynamic entities: both their conformation and catalytic activity fluctuate over time. When such fluctuations are relatively fast, it is not surprising that the classical Michaelis-Menten (MM) relationship between the steady-state enzymatic velocity and the substrate concentration still holds. However, recent single-molecule experiments have shown that this is the case even for an en...

ESTIMATING THE PARAMETERS OF THE MICHAElIS - MENTEN EQUATION USING SAS

The Michaelis-Menten equation, a rectangular hyperbola with two ~arameters ~o b~ specified, . occurs prominently 1n enzyme k,netlcs." Often, ~n consulting situations we need to (i) obtain estlmates standard errors, and confidence intervals for the unknown parameters, which define this nonlinear model for one set of experimental conditions and (ii) compare the parameter estimates under different...

The 'double' Michaelis-Menten equation: estimation of parameters.

When the concentration dependence of an enzymic reaction or a transport process can be described by the sum of two Michaelis-Menten terms, reliable data that relate reaction rate and substrate concentration can be obtained even when as much as 70 per cent of substrate was consumed during the assay. Each data pair consists of the average reaction rate during an assay and the concentration where ...
